General Nonsense.

Dear Diabetes,

I woke up this morning with a nice blood sugar. It was 143 mg/dL. I calibrated my CGM and then lowered my basals, just like I do before every run I go on. When I got back I was at 150 mg/dL which was also nice. Then we went to breakfast and I carb counted my meal perfectly. I also bolused extra in anticipation of a post-workout, liver-induced high BG. I did everything I was supposed to do. And this is how you repay me:












You are a jerk. That is all.

Sucks. I’ve been running more in the early morning, before work and having a bear of a time with the post-workout spike.

I ate a healthy low carb salad for lunch today…bolused…and had that exact same line on my dexcom. You win this round diabetes!

I say smash it!!!You can’t believe everything you read! 🙂 Just kidding, hang in there! xo

Happens to me too on my bike rides. For shorter rides of less than one hour, I don’t reduce my basal rate and eat a banana before starting instead.

The only thing that has ever worked for me to combat post-workout highs is Symlin, and without a new doctor up here in Portland I have not jumped back on that bandwagon yet.

My doctor has never suggested Symlin for me but I’m curious. Do you think I should try it?

I find this a very curious thing. The only time (so far, and maybe my perception is skewed) I’ve read about post-exercise highs is on English language boards (err.. and I’ll freely admit that I can only read English and German).

This topic has never cropped up here (as far as I know) and we are typically taught that the refilling of muscle/liver glycogen will instead reduce blood sugar levels for some time after exercise.

The German version (reduced insulin needed after sports) affects me. After short stints (less than an hour), I’d calculate 20% less basal rate for three hours or so, after day-long exercise I’ll reduce basal rate by 30-40% for up to 24 hours. And eat more, typically.

Really weird this 🙂

Mike I loved the results I had with Symlin. It’s a tough ramp-up, it will cause nausea initially but if you titrate up slowly, it’s doable. People with Type 1 don’t make insulin obviously, but the destruction of our beta cells means we also don’t make the hormone Amylin. Amylin’s job is to tell the liver “Hey, no more glucose needed over here, we’re eating now!” Without it, your liver will keep the glucose flowing post-workout and raise your BG. Taking artificial insulin like we do doesn’t help right away. The analogy I use is that taking artificial insulin is like mopping the floor when the bathtub is over flowing. Taking Symlin is shutting off the faucet. I loved it, I’d recommend trying it!

Floh – you seriously don’t get high BGs after some of your workouts? Particularly in the morning on an empty stomach? That’s when the liver really kicks in to over drive. If you are not, I need to do whatever you’re doing!? What time of day do you usually work out?

“Workout” is probably being generous 🙂

I usually go to work and back at 7.30 and 17.30. The morning one is either empty stomach (if I’m late) or with half breakfast bolus. The evening one is empty stomach (I think that actually counts, as my lunch break is usually between 12.00 and 12.30).

On all those my blood glucose drops by 100 – 150 mg over the half hour. I tend to compensate with 300ml of coke before starting, which isn’t always enough (not entirely surprising, in retrospect. That amount only raises my blood sugar by 60 to 120).

I drop my basal rate one hour before starting, then set it back to normal at starting time. With my insulin-speed this means I’ll start spots on “less basal rate” and it will ramp up back to full roughly 15 to 30 minutes after I finish (and yes, this basically means my “sports” are 30 minutes).

In the mornings my blood glucose keeps dropping after sports end. In the evenings I tend to make dinner and can’t really say.

I’ve not experienced sugar levels raising yet, though.

Floh I thnk you’re not usually experience a spike in BG because you have your basal rates tied in perfecty! And clearly, exercise runs the risk of dropping you too low, instead of high, so there’s a counter balance already built in. I always say people with diabetes are like snowflakes – there are no two alike!
